PCI Express 6PIN to Molex 4 PIN conversion

I recently bought a dell XPS 8300 which has two open 6 PIN PCI Express power supply plugs. I wanted to upgrade the sound card to a Xonar Essence STX card. My problem is that the STX needs a Molex (LP4) power supply and the dell only has 6Pin PCI Express plugs. Can I convert the PCI Express plug to a Molex (LP4) female plug? IF so, how and what cables do I need? I can find cable to convert 4PIN to 6PIN, but not 6PIN to 4PIN.

Thanks in advance for help.

Hello M_Go_Blue;


Do you have an extra SATA power lead?

The PCI-e graphics connectors only supply 12V.
With the SATA to Molex you're getting the Essence STX card 12V and 5V which is what the Molex connectors usually provide.
